Sealos offers a flexible environment where containers can be effortlessly created and destroyed. This flexibility is advantageous for application deployment and management, but it also raises the issue of maintaining data persistence. In scenarios where data is stored within an application container, its destruction leads to the loss of all stored data.
To counter this problem, the use of persistent storage is essential. Persistent storage ensures that data is stored externally, thereby preserving it even through container restarts or redeployments. This is particularly vital for applications requiring data retention, like databases, file storage systems, or any services involving user data.
For instance, in deploying Nextcloud, all data associated with its container is located in the /var/www/html directory. To maintain data continuity, it's necessary to use external storage solutions for persisting data in this directory.
